Default cracking clear coat on Cowl

I have just over 58 hours on my 9A and I now have spider cracks in my clear coat, its not down to the paint just in the clear. The location is a little forward of the oil door. My observation says it might be the top cowl expansion while in flight. The bottom cowl is open where the 2 exhausts come out plus I added while building on each side of the bottom cowl 4X12" louvers. My temps are good EGT's at 340 and CHT at 1260. What have other flying 9 builders done to get the forced air through the cowl. Pictures would be helpful.. Thanks, Mark C. 119RV
